[−][src]Struct memory_lru::MemoryLruCache
An LRU-cache which operates on memory used.
Implementations
impl<K: Eq + Hash, V: ResidentSize> MemoryLruCache<K, V>[src]
pub fn new(max_size: usize) -> Self[src]
Create a new cache with a maximum cumulative size of values.
pub fn insert(&mut self, key: K, val: V)[src]
Insert an item.
pub fn get(&mut self, key: &K) -> Option<&V>[src]
Get a reference to an item in the cache. It is a logic error for its heap size to be altered while borrowed.
pub fn with_mut<U>(
&mut self,
key: &K,
with: impl FnOnce(Option<&mut V>) -> U
) -> U[src]
&mut self,
key: &K,
with: impl FnOnce(Option<&mut V>) -> U
) -> U
Execute a closure with the value under the provided key.
pub fn current_size(&self) -> usize[src]
Currently-used size of values in bytes.
